Fig. 1a, a view similar to Fig. 4, witlithe latch bolt and its yoke removed;

Fig. 14, a similar view broken away with the operating hubs removed and showing the inner end of the outer knob spindle; and

Fig. 15, a cross section of the look with thehubs in place;

Fig.- 16, a side view in elevation of the inner side of the face plate;

Fig.17, a section on the line y-y .of Fig. 16;

Fig. 18, an inside view of the removable cover.

In all figures, similar letters of reference re resent like parts. eferring to the drawings, 1 is the outer escutcheon and 2 the inner escutcheon.

Formed integral with the outer escutcheon plate and extending at an angle theretois a face plate 3 provided with an opening through which projects a latch bolt 1 pivotally mounted on a pin 5 extending across and through the face plate.

This pivoted latch bolt within its center line has a pivot pin 6 which extends through a central slot 7 and side slots 8, formed in the inner part of the latch bolt. Extending into the side slots 8 are inwardly inclined arms 9 having elongated slots 10 engaging said pin 6. (See Fig. 11.) These arms are integral with a forked yoke 11, the branches of which have outwardly projecting arms 12. These arms are adapted to take over and engage the wings 13, 14, and 15 of operating hubs 15', 16 and 17, which are concentrically mounted.

The outermost hub 15 is oierable bv the shank 18 of the outside knob 19. This shank at its inner end is provided with a head havin; a recess 20 adapted to seat a projecting boss of the hub 15', which boss is provided with two diametrically opposite lugs which the edge portion of a two-part plate 23, surrounding the shank opening and fixed to the inner face of the escutcheon 1, whereby the knob and its shank are held rigidly against longitudinal withdrawal, while at the same time free rotation thereof is permitted.

' face of the outer knob.

The inner hub member 17 is provided with an elongated sleeve and has a squared or otherwise angularly formed opening in its inner end with which is adapted to engage the similarly formed spindle 27 of an inside knob 28. The shank 29 of the knob is provided near its inner end with a circumferential slot or groove. 30, into which projects the edge of a two-part plate 31 which is rigidly secured upon the ledge 32 on the inner face of the escutcheon 2.

The outside hub 15 is provided with a laterally projecting lug 33, which is adapted to be engaged by a movable member of a suitable night latch mechanism for the purpose of deadlocking the outside knob. To this end, a manually operable deadlocking slide'34 is mounted on the inner face of the outside escutcheon '1, and is provided at its inner end with a slot 35 adapted when the slide is pushed inwardly to engage said lug 33 so as to hold the hub 15 against rotation. The slide has a forward inclined arm 36 which is provided with a thumb stop member 37 projecting through the face plate. A beveled tooth 38 projecting laterally from the slide is adapted to engage the bent end of a spring 39 which serves to yieldingly hold the slide in the position to which it may be adjusted. (Fig. 13.) guide lug 40 projects inwardly from the slide and serves to limit the outward movement of the yoke and guide the latter in a straight reciprocal movement.

The slide has a pin 41 projecting toward the escutcheon and engaging a notch in the end of a walking beam 42 which is centrally pivoted and serves to operatively connect said deadlocking slide with a releasing thumb-stop slide 43 projecting through the face plate. When the thumb stop 43 is pressed inwardly such movement withdraws the slide 34 from deadlocking position.

Between the arms of the latch bolt yoke a standard 44 projects from the inner face of the eseutcheon 1.. The standard 44 has interiorly threaded posts 45 adapted to receive the ends of screws 46, passing through the cover hereinafter described. Between these posts a bearing is provided for a reciprocating latch bolt stem or rod 47 pivoted at its outer end to the latch bolt and surrounded by a spiral spring 48 held between the standard and a collar 49 loosely secured to one of the arms 9. (See Fig. 16.) This spring serves to normally hold the latch bolt protracted. The latch bolt rod 47 on which the spring is mounted is pivoted to the latch bolt pin 6 within the middle slot 7, as shown in Fig. 17.

Projecting through a flange 5O joining the face plate and the escutcheon 1 is an automatic dogging member 51, which has a sliding movement in said flange approximately parallel to the face plate, and the outer end of which is adapted to contact with the striker plate or jamb when the door is closed for the purpose of sliding the member inwardly into dogging position. This member is adapted not only to dog the latch bolt, but also the night latch mechanism, and serves to prevent the retraction of either of said mechanisms by an instrument inserted between the door and the jamb. This member 51 has a stem 52 surrounded by a spiral spring 53 which serves to keep theouter end of the member normally protracted when the door is open. A shoulder 54 limits the outward movement of the member 51.

A ledge 55 projecting inwardly from the member 51 and a shoulder 56 on said member are adapted to cooperate with a latch bolt stop member 57 pivoted at 58 to the latch bolt in one of the slots 8 and provided with a lug 59, which the shoulder .56 is adapted to engage for the purpose of preventing the retraction of the latch bolt.

The pivoted stop member or dog 57 is provided with a rounded cam-shaped tail piece 60 (Fig. 11) which bears against the ter is in its inner dogging position.

The said dogging member is adapted also to dog the night latch mechanism when the latter is in dogging position and to this end,

it has a lug 61 which, when the deadlocking slide 34 is in retracted position, is moved into a recess and in front of a shoulder 62 of said slide by the incursion of the dogging member upon the closing of the door.

The dogging member is provided with a 2 lug 63 which serves as a guide for the sliding yoke connection to the latch bolt.

Adapted to inclose the operative parts of the lock and to retain them in place is a cover 64 having an aperture for the inside knob shank, and apertures 65 corresponding to the screw holes in the posts of the supporting standard 44 projecting from the escutcheon.

This cover is also provided with an aperture 66 to receive the end of the stem of the dogging member 51. The spring surroundmg sald stem bears against the inner face of the cover.

Secured to the inner face of the cover is' a flat spring 67 adapted to bear against the lug 59 of the stop member 57 so as to tend to carry said member into line with the.

shoulder 56 of the dogging member.

The cover 64 is entirely free of one (the inside) escuteheon and it is spaced from said escutcheon as shown in Fig. 3. The

cover is of box-like form having opposite.

side walls and an end wall with edges in abutment with the inner surface of the other (the outside) escutcheon. At the other end means for detachably securing the cover in place, and the latter may therefore be very readily assembled in the lock structure. The

several screws for adjustably connecting the escutcheons are preferably located outside of the cover and the latter may be rigidly.

carried by the outside escutcheon when the inside escutcheon is entirely removed.

The rod 47 on which the spring 48 is' mounted is simply set at its inner end in the notch in the standard 44 which lies between.

the cover securing posts or lugs 45. In this manner the spring action 1s lmparted to the bolt in a simple and effective manner without the necessity of a special spring or springs acting directly on the yoke.

The dogging member 51 is very effectively guided in its rectilinear movement, inasmuch as it has a hearing at one end in one cover and the inside face of the outer escutcheon without the interposition of any special retaming member. In other words,

the inner or back wall of the cover, in forming a bearing for the hub of the inside knob,

and holding said hub in cooperation withthe other hubs, secures the hubs effectively in place without the necessity of providing another hub retaining wall on the cover to cooperate directly with the hub of the outand having a notch therein at its free end, a

of the integral outside escutcheon, and the parts may be readily and quickly assembled by first placing the latch bolt and yoke in position, then inserting the dogging member into its socket, and then placing in position the deadlocking night latch members.

Each knob shank is held rigidly to its respective escutcheon and can only be with- I drawn byremoving said escutcheon, and then unscrewing the shank therefrom.

After the latch bolt mechanism has been mounted on the outside escutcheon, the cover is put in place and screwedon and then the inner escutchcon attached.

Assuming that the night latch mechanism is off when the door is closed, the projecting end of the dogging member 51 will strike against the striker plate or jamb and the shoulder 56 of the dogging member will be carried behind the lug 59 of the stop member 57 pivoted to the latch bolt,

thus preventing the retraction of said latch bolt by an instrument inserted between the face plate and the jamb. In such position, however, the latch bolt may stillbe retracted by the yoke through actuation thereof by the inneror outer knob or the lock in. the knob, each of which actuating parts is operatively engaged with its respective winged hub. 7

When any of the hubs is turned, the yoke will be retracted and the arms 9 rigidly con- .nected thereto will have a slight inward movement relative to the latch bolt by reason of the elongated slots 10 so that the upper arm 9 will also move relatively to the stop member 57 and thus carry the flat inner face of the arm against the tail piece cam 60, thus tilting the stop member or dog 57 and carrying the lug inwardly away from the dogging member, permitting the latch bolt to be retracted.

When the night latch mechanism has been set prior to closing the door, by pressing inwardly thumb stop slide 3a to engage its slot 35, with the lug 33 of the outside hub,

the dogging member is carried inwardly to a the same position as before described as the door is closed, and thereupon in addition to dogging the latch bolt, thelug 61 is projected inwardly in front of the shoulder 62 so as to prevent the deadlocking slide 34 from being pushed outwardly by pressure on the slide 43.
